Famous British hoaxes

If you're ever wandering down Leinster Gardens in Bayswater Road in London,
take a careful look at Numbers 23 and 24. These houses are in fact just
facades, built to disguise an exposed part of the Metropolitan underground
railway that runs behind them. In the 1930s, a man famously sold hundreds of
guests tickets to a black tie charity ball there – only for them to turn up
and discover the houses were fakes.
